Hat-pin.



yof the borough of Brooklyn, city of New l York, in the county of Kings and State of l New York, have invented certain new and Aiace A. Roimms,

useful improvement. in flat-Pins, of which l the following is a specification.

'lhe genei'al type of hat worn by women is so coiislructed and litted that it requires ll n means other than the hat itself, or t-lie f parts thereof for securing it in place upon l the head of the wearer. For that purpose certain types of instruments, hatpins have l been long used. 'llie more common typel of hat pin is one which is readily witidrawn completely from the hat, but there t z is another kind of hat pin, one which serves i,

without'. complete separation from the hat'. and my invention is of this class.

l provide means for readily passing the I hat. pin through one side of the hat, and l provide an ornainenlnl head for the exter-4 nal cud of my pin. but. in addition to thisi I provide a ibcral shield having a metall center. which is slidable upon the inwardly extending part of the iin.

. best means of carrying out. my invention.

The following is wiat I consider the li which the groove for the fiber disk is noti about the center periphery.

Similar letters of reference indicate like` parts in all the figures where they appear. A indicates the pin, a head A* is attached to the main body of the pin by screw threads, and the end of the pin, upon which lthe screw threads have been produced is also provided with al sharpened point forv it is this end of the pin, thatl is forced outward through the crown of the lint. The inwardlv extending point of the pin A is tliitteiied and caused to assume a shape not unlike a spear head, though any sharpness which has been caused hy shaping must be carefully removed as this portion of the. instrument is intended to be smooth and well rounded.

The shield is composed of two main parts, the disk B. and the center metallic portion. B. The disk may be of metal, but l prefer to make it of felt, and have so operatedl in my experiments. In thickness it is abouti one-eighth of an inch. and although this ist not important. it should be sutliciently firm sulliciently large to fit snugly about the bot.- toin of a groove or recess with which it.

is designed to operate. The metal part li is a solid globe or ball. A hole b sufliciently large to fit loosely about the pin A is bored quite through the axial center et the hall. One end of the hole b is countersunk to form a recess b, properly shaped and of.

sullieient depth to accommodate the spear shaped point of the pin A as shown in; Fig. 4. About the peri ihcry of the ball ll,`

and at rightI angles to t ie hole I is a roove b". Its width exactly equals the thickness of the washer B, an its de ith is suflieient to retain the washer reliably when it has been forced over the ball and allowed to contract within the slot. b.

lu the inanufaelure. the parts are. each properly shaped and linislied and the hole xiii tlie disk li is expanded and allowed to ycontract. iu the groove of the pai't. li.

l"or fear ol' iuadvciteiit. displacement the edges ol the groove. b2 ai'e upset or turned in, iu such a iiiauuer as to elainp the disk ll securely in place. 'l`lie completed shield -is then strung upon the body of the pin, `eare being taken to so relation the, parts that. the spear shaped point of the. pin will ind a natural and ready resting place within the recess 7,2. 'l`he sharpened screw tlu'eaded point. of the. pin is now thrust through the crown of the hat. and the head is b v means of the screw threads secured to the main body of the. pin, and my device is now ready for operation.

l iittacli importance to the construction und operation of the fibrous disk ll and its metallic center B. because the metallic een- `ter accepts, shields and provides a firm bearing for the point. A of the pin A and Abecniise it is well adapted to side easily inlong the pin and more especially because the tibi'ous disk readily assumes a position between the lint and head et the wearer which causes no discomfort.-

Modifications within the sco ie of the appeiuled claims may be made liy any goed mechanic.

llaving carefully and fully described my invention what l claiin and desire to secure hy Letters Patent iszl. A hat pin having one end latteiied,

`the other end screw-thrcmled and sharpcned and having a head adapted to serve upon the screw-threaded end in combination y with ii fibrous disk and a metallic member adapted to slide longitudinally upon said pin, said metallic incniber being provided with a recess for the ieceptioii of the flat.- tened end ot the pin, and a circumferential groove for the reception of the said fibrous disk as spccitied.

42. A hnt pin having one end Ihdtcned,

= the other end screw-threaded nud sharpened und having n hend adapted to serve upon the, screw-threaded end in combination with :x fibrous disk und n` metallic member udupted to slide longitudinuliy upon seid4 v pin, Suid metallic member being provided with n recess for the reception of the luttened end of the pin, und n circumferential I groove for the reception of the seid fibrous disk, und having menus ndjucent, to said groove for securing Suid disk within seid groove ns specilied.
